My master's thesis presents the development and implementation of activities outlined for the chapter of the photoelectric effect with secondary school students. The purpose of the activities is to acquire and deepen the understanding of the students’ knowledge of the photoelectric effect. The activities have been carried out during live classes with students of the third-year of general secondary school programme. Students investigate the concept of the photo effect by means of the investigative science learning environment (ISLE). Half the class use a simulation in their activities, while the other half do not. Each class has also been recorded. On the basis of the students’ replies on their worksheets and the analysis of the video clips we have conducted a survey of the success of doing certain tasks on the students’ worksheets and made a comparison of the two groups of students.
The introduction of the thesis presents the theoretical background of the research of the activities conceived. The students’ responses as well as the entire process of the classes are presented in detail. Based on the findings an analysis of the data using rubrics for self-evaluation is conducted. Finally, the conclusion of my work points out the issues experienced by the students while executing certain activities. Furthermore, it incorporates the suggestions that would aid the process of activity solving and aims to answer the research questions of my thesis.
